STEAM-RADIATOR.

SPECIFICATION forming part of Letters Patent No. 313,883, dated March 17, 1885.

` Application iiled June 24, 1884. (No model.)

To all whom t may concern:

Be it known that I, LEON H. FRENTIGE, of Vaukegan, i-n the State of Illinois, have invented certain new and useful Improvements in Steam-Radiators, of which the following is a specification.

The invention relates to steam-radiators used `for warming offices and apartments of buildings; and it consists in the construction, arrangement, and combination of parts, hereinafter described and claimed, for regulating the heat.

The accompanying drawings illustrate the invention.

Figure l is a side elevation of asteam-radiator containing the invention, portions being broken away to show the interior construction. Fig. 2 is a sectional plan view of the same. Fig. 3 is a top view of a portion of the radiator. Fig. 4. is an enlarged sectional plan view of a portion of the same.

A A A designate the heaters. B is the base, and B the top. The base, as represented, is formed of three independent compartments, b b b, having no communication with each other, and the heaters A A All connect and communicate, respectively, with the compartments of the base, so that the heaters A, with the compartment b of the base,and A b', Src., constitute each distinct parts of the radiator independent of each other.

Gis the pipe for conducting the steam to and into the radiator. A valve, G', is placed at the junction between the pipe and the radiator, and three ports, ce a a, connect the compartments b b b, respectively, with the pipe through the same valve C. The valve is hollow and open at the bottom, and has a wide side opening, c c, sufficient to cover all the ports at once. The valve is preferably made tapering and compressed by a spring, s, into its seat of corresponding taper for compensating wear. An operatingrod, D, is connected with the valve and provided with a handle, D', and a dial, E, and index e are attached to show the position of the valve, as when closed or open, or having one or more of the compartments open. A spring-pawl, e', engaging with notches e in the edge of the dial-plate, is provided for setting or xing the valve in any of its desired positions.

The drawing, Fig. 1, shows the operatingrod extended up through one of the end heaters and through the top B, with the dial on the top. With this construction the valve g should be open at the top, as at o', to allow the steam to pass up into the heater having the rod thus extended up through it. When the valve is made tapering and seated in a tapering seat, as shown, it is also necessary to have this opening o', to prevent the steampressure from compressing the valve so tightly in its seat as not to be easily turned. The steam from pipe C passes through the valveopening c c, and thence through the portsaa a into the compartments b A b A b A. Moving the handle D to the extreme left or notch nearest closed,77 (marked on the drawing, Fig. 3,) turns the opening c c away from all the ports and closes all of them. Moving it thence to the right one notch opens the iirst port, a, and heats only the corresponding compartment b A. Moving it one notch farther opens the second port, a, without closing the first, so that an additional compartment is heated, and so on until all the ports are open and the whole radiator is filled with steam and heated. By a reverse movement of the handle the steam is shut off from one or more of the compartments, as desired, after the room has been sufficiently warmed to require only one or more or less than all of them to maintain the temperature withoutincreasing it.

I am aware that steam-radiators made in two or more compartments and having a separate 'valve for letting steam into each compartment have heretofore been used; but this construction does not constitute my invention, which consists in the combination of a radiator with one or more compartments with a single valve located between the junction of the inlet-pipe and the radiator and connected with a separate port for each compartment of the radiator, whereby the whole or one or more of the compartments may be operated by the single valve in such manner that only a portion of the radiators may be used in mild weather, when only a little warmth is required, and a greater portion or all of them at other times when more warmth is required, andthe radiator may be made with two or any greater number of compartments, the one valve governing them all being made to correspond and operate in connection with a steam-port from the inlet-pipe to each of the compartments through the one valve, and the dial being made to correspond.

The arrangement of the handle of the valve on the top by running the rod D up through one ofthe radiator-pipes, as shown in Fig. 1, is a new and convenient arrangement; but the valve may be located outside of the base at the end, and the operating handle and dial be placed at the bottom Without materially changing the combination of the single valve with a compartmentradiator.

1. As an improvement in steam-heating apparatus,the radiator composed of two or more independent compartments, each having a separate port, in combination with an inletpipe, asC, and a single valve, as C', operating in connection with all the ports, substantially as and for the purpose specified.

2. As an improvement in steam-heating apparatus, the radiator composed of two or more 2 5 independent compartments, each having a port, in combination with a single inlet and valve and a dial, as E, substantially as and Yfor the purpose specied.

3. As an improvement in steam-radiators, the valve, as C', in combination with the rod, as D, extended up through one of the radiator-pipes to the top of the radiator, and having a handle and a dial, as E, all arranged substantially as shown.

4. The steam-radiatorhaving compartments b A, b A', and b A, inlet-pipe C, valve C', operating-rod and handle D D", and dial E, all constructed and arranged substantially as shown.
